The promo clip for the episode is pretty vague. All the apparent parallels with the Kari Ferrell case are, 1. An Asian woman is involved, and 2. There appears to be some illicit sexxxy action going on. That said, this plot summary from an NBC message board really doesn't sound like the dynamic grifter we know and love:

A CRIME SCENE INVESTIGATOR IS FOUND DEAD WITH HER UNFAITHFUL FIANCE AS THE PRIME SUSPECT. HOWEVER, WHEN A YOUNG JOURNALIST IS ATTACKED AND LINKED TO THE CRIME, THIS OPEN-AND-SHUT CASE MAY NOT BE AS SIMPLE AS IT ORIGINALLY SEEMED.
After CSU investigator, Daisy Chao, is found murdered in her apartment, Detectives Cyrus Lupo (Jeremy Sisto) and Kevin Bernard (Anthony Anderson) suspect her fiancé Jim Anderson may not be telling the whole truth about his involvement with the murder. When young journalist, Emma Kim (Guest Star Camille Chen), is attacked by a cab driver, DNA found at both crime scenes seems to implicate the same man for the attacks. The investigators become personally involved with the case as Detective Lupo gets close with Emma, and ethical questions arise. Also starring: S. Epatha Merkerson (Lieutenant Anita Van Buren), Sam Waterston (District Attorney Jack McCoy), Alana De La Garza (Connie Rubirosa), and Linus Roache (Michael Cutter).

This would require the Grifter character to be a journalist. Doubtful.
